GAGE FOR BORING-MACHINES.

Specification of Letters Patent.

Patented June 20, 1911.

Application filed July 18, 1910. Serial No. 572,529.

To all whom it may concern:

Be it known that I, ANTON J. I-Ion'rrr, a subject of the King of Norway,residing at Rochester, in the county of. Monroe and State of New York,have invented certain new and useful Improvements in Gages forBoring-Machines, of which the following is a specification.

This invention relates to new and useful improvements in gages forboring machines, and is designed particularly to construct a device ofthis nature wherein the same will be operative on both sides of thedrill, and also which will be adjustable to various sizes of blocks.

With the above and other objects in view, this invention consists in theconstruction, combination and arrangement of parts all as hereinaftermore fully described, claimed and illustrated in the accompanyingdrawings, wherein:

Figure 1 is a perspective view of a gage constructed in accordance withthe present invention, illustrating the cooperation thereof with a drilland a block of wood adapted to be pierced with holes; Fig. 2 is afragmentary vertical section taken through the gage, illustrating themounting of the clamping member and the journaling of the gage platecarrying rod; Fig. 3 is a section taken through the gage plate carryingrod, illustrating the mounting of the gage plates thereon.

Reference being had to the drawings, 10 indicates a table of a gageconstructed with the horizontal or base side 10 and the vertical side 10A central vertical opening 11 is provided in the vertical side 10 andsup plies a means whereby the drill may be operated therethrough. Ateach end of the vertical side 10 are provided the brackets 12, saidbrackets being provided at their upper ends with the cars 13. Betweenthe cars 13 are pivoted the supports 1 1 which are adapted to normallyextend over the horizontal side 10 each of said supports being providedwith an enlargement or off-set portion 15 which forms a bearing supporton the upper edge of the vertical side 10.

A plate 16 is mounted on the upper edge of the vertical side 10 and isprovided with the central ears or lugs 17 between which is pivoted thehorizontal bearing 18, said bearing being provided with a reducedportion 19 at its outer terminal. A rod 20 having the orificedenlargement 21 at one terminal thereof is mounted on the reduced portion19 through the instrumentality of said enlarged portion and retained inthis position by the nut 22. A longitudinal groove 23 is provided inthis rod through the instrumen tality of which the gage plates areretained in their vertical positions as hereinafter more fullydescribed. This rod 20 is adapted to swing about the bearing 18 and reston either of the supports 14, and consequently is adapted to provide ameans whereby a block may be gaged on either side of the opening 11. Aplurality of collars 24% are mounted on the rod 20, each of said collarsbeing provided with a set screw 25 which is adapted to project throughsaid collars and engage the groove 23 in the rod when the gage platesare in their normal positions. The plate 27 may rotate about the rod 20without in any way moving the collars 24:. By this construction it willreadily be understood that the various positions of the plate may beretained without shifting the collar when it is desired to place thesame in inop erative positions. These collars are provided at one endthereof with the upwardly extending flange 26, said flange being adaptedto be received in a recess in the gage plates 27 and are retained inthis position by a clamping ring 28 bearing on said flange, and held inthis position by the screws or rivets 29. The gage plates 27 may eitherbe substantially straight in construction or off-set as is illustratedin Fig. 1, all of said clamping plates having at their lower terminalsthe studs 30 which are adapted to engage the end of the block on whichthe drill is operated and retain the same from lateral displacement.

A handle 31 is pivoted between the walls of the opening 11 adjacent tothe plate 16 and is provided adjacent to the vertical side 10 with theflattened portion 32 in which is adjustably mounted the rod 33, said rodcarrying at its lower terminal the clamping block at, and at its upperterminal the nuts 35, said nuts being adapted to regulate the heightofthe block above the base or horizontal side 10 The pivot of the handle31 comprises a pin 36 located transversely in the opening 11 whichengages an enlarged bearing 37 formed at the extremity of the flattenedportion 32.

From the foregoing it will readily be understood that the blockindicated as A may be operated upon by the drill as illustrated indotted lines and after the first hole is bored, the first gage plate ismoved, permitting the block to bear against the second gage plate and soon, thus permitting a series of openings or holes to be drilledin theblock. If the block is too long to permit of its being pierced itsentire length, the rod 20 is swung over to rest on the opposite bearing1% when the operation is completed as heretofore described.

Having thus described the invention, what is claimed as new is:

1. A gage of the class described, comprising a table having an openingtherein, a bearing superposed above said opening, a rod pivotallycarried by said bearing adapted to operate on either side of saidopening, and means carried by said rod whereby the material operatedupon may be gaged.

2. In a gage of the class described, the combination with a table havinga central opening therein, a rod pivotally mounted adjacent to saidopening adapted to operate on either side thereof, and plates adjustably carried by said rod adapted to locate the material beingoperated upon in difierent positions with respect to the bit.

3. In a gage of the class described, the combination with a table havinga vertical back thereon, said back having a central opening, a bearingsuperposed over said opening, a rod pivotally mounted on said bearingand adapted to operate on either side of said opening, and means carriedby said rod for gaging material.

4. In a gage of the class described, the combination with a table havinga vertical back thereon, said back having a central opening, a bearingsuperposed over said opening, a rod pivotally mounted on said bearingand adapted to operate on either side of said opening, plates adjustablymounted on said rod, and a support pivotally mounted on each terminal ofsaid table back adapted to lift the end of said rod.

5. In a gage of the class described, the combination with a table havinga vertical back thereon, said back having a central opening, a bearingsuperposed over said opening, a rod pivotally mounted on said bearingand adapted to operate on either side of said opening, plates adjustablymounted on said rod, a support pivotally mounted on each terminal ofsaid table back adapted to lift the end of said rod, collars adjustablymounted on said rod, and plates pivotally connected to said collars.

6. In a gage of the class described, the combination with a table havinga vertical back, said back having a central opening therein, a bearingmounted on said back directly over said opening, a horizontal bearingpivotally mounted in said bearing, a rod pivotally mounted on saidhorizontal bearing, and gaging plates adj ustably carried by said rod.

7. In a gage of the class described, the combination with a table havinga vertical back, said back having a central opening therein, a bearingmounted on said back directly over said opening, a horizontal bearingpivotally mounted in said bearing, a rod pivotally mounted on saidhorizontal bearing, and horizontal bars pivotally mounted at theterminals of said back adapted to support the terminal of the rod, andgage plates adjustably carried by said rod.

In testimony whereof I aflix my signature in presence of two witnesses.

ANTON J. HOLTH.
